更新片段

Question

当我更改微分值时，即使TAB1处于活动状态并显示在屏幕上，图表也会在TAB2上更新，但不会在TAB1中更新。

这是我的代码......

onCreateView：

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
   rootView = inflater.inflate(R.layout.fragment_charts_line, container, false);

    layoutChart = (LinearLayout) rootView.findViewById(R.id.chart);

    ...all renderer settings...

return rootView;

onViewCreated：

public void onViewCreated(View view, Bundle savedInstanceState){

    Toolbar mToolbar = (Toolbar) getActivity().findViewById(R.id.toolbar_actionbar);
    final Spinner spinner_nav = (Spinner) mToolbar.findViewById(R.id.spinner_nav);
    spinner_nav.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
            cSpinner = spinner_nav.getSelectedItem().toString();
            showChart(cSpinner);
        }
        @Override
        public void onNothingSelected(AdapterView<?> parent) {
        }
    });

    cSpinner= spinner_nav.getSelectedItem().toString();
    showChart(cSpinner);
}

showChart：

public void showChart(String account){

    if (mChartView == null) {
        LinearLayout layout = (LinearLayout) layoutChart.findViewById(R.id.chart);
        mChartView = ChartFactory.getTimeChartView(layoutChart.getContext().getApplicationContext(), mDataset, mRenderer, "MMM yyyy");
        layout.addView(mChartView, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
    } else {
        mChartView.repaint();
    }
}

我想要的是更新每个标签中的所有图表，或者至少更新当前标签中的图表。每个选项卡片段中的每个变量名称都不同。
